AIS Gap Analysis: Reading What Vessels Try to Hide

A four-day silence in the South China Sea is not a satellite issue. It is, more often than not, a decision.

Vessels do not "disappear" from AIS. Operators turn off transponders for reasons that, taken together, paint a recognizable pattern. Here is how we read the silence.

ADS-B Off: Why Aircraft Stop Broadcasting, and What Their Silence Tells You

What Private Jet Pattern-of-Life Quietly Reveals About Their Owners

Aircraft do not lie about where their owners actually live, sleep, and meet. The pattern is in the schedule, not the registration.

A registered owner is a legal fiction. A flight schedule, six months deep, is a behavioural fact. The two are rarely the same person.
